SOLAR TRACKING-TYPE PHOTOVOLTAIC POWER GENERATION SYSTEM CONTROL DEVICE AND SOLAR TRACKING-TYPE PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

Provided is a solar tracking-type photovoltaic power generation system control device that can suppress a decrease in the amount of power generation, the decrease being due to a retraction control. A solar tracking-type photovoltaic power generation system 1 includes a solar cell 2 and driving means 3 that inclines and rotates the solar cell 2 so that a light-receiving surface 2b of the solar cell 2 tracks the sun. A control device 4 of the solar tracking-type photovoltaic power generation system 1 includes posture detecting means 11 that detects an inclination posture of the solar cell 2, wind-speed measurement means 12 that measures a wind speed, a setting part 13 that sets a first wind-speed threshold value V1 each time in accordance with the inclination posture of the solar cell 2 detected by the posture detecting means 11, and a control part 14 that performs a retraction control in which, in a case where a wind speed value measured by the wind-speed measurement means 12 exceeds the first wind-speed threshold value V1, the solar cell 2 is laid down by the driving means 3 and is positioned in a retraction posture.
